by Dionex
The IonPac® AS7 separates a wide variety of polyvalent anions, including polyphosphates, polyphosphonates, and other polyvalent complexing agents such as EDTA and NTA using acidic eluent (eliminating metal interferences) with postcolumn derivatization and UV-Vis detection.
The AS7 column has a unique polymer packing that provides superior performance for separating ionic and polar compounds. The patented packing offers high speed, high efficiency, and high loading capacity at moderate backpressures.
